This paper provides an in-depth look at the various factors that influence the World Happiness Index and the extent to which these factors influence the Global Happiness Index. By analyzing several aspects of the study, including factors such as economy, social support, health, freedom, honesty and corruption perception, and generosity, the unique role of these elements in constructing the happiness index is revealed. The study found that there are significant differences in these factors across countries and regions, which directly impacts their overall happiness index rankings. By gaining a deeper understanding of the degree of influence of each factor, we can gain a more comprehensive understanding of the mechanism of happiness formation around the world, which provides an important reference for the formulation of happiness-enhancing policies and measures. This research provides insights for promoting global well-being and building happier and better societies.

This article analyses the body narrative in the film Portrait de la Jeune Fille en Feu from a feminist perspective, exploring the gendered power structures implicit in the female characters' bodily expressions and discussing how it constructs and reflects feminist theories. The article reviews the development of feminist theory, emphasises the importance of body narrative theory and its application in film studies, and chooses the film Portrait de la Jeune Fille en Feu as the object of study. Through textual analysis and feminist critical theory, this study dissects the body narratives of the female characters to reveal how visual language and symbols shape the body's position in gendered power relations. It is found that the female body narratives in the film are not only an expression of subjectivity, but also a response to social power structures, demonstrating the deep connection between gender, power and self-identity.

Functional load (FL), which ranks segmental contrasts based on their communicative value in pronunciation, is essential to the development of pronunciation instruction in that it indicates the priority of certain segmental contrasts that may seriously affect the intelligibility and comprehensibility of spoken language for English as a Second Language (ESL) learners. Despite the widespread use of FL in pronunciation pedagogy for ESL learners, there is little evidence on whether FL affects ESL learners’ perception of vowel contrasts. In this paper, 20 ESL learners from two Chinese universities are selected to participate in two tasks to observe their performance in discriminating vowel contrasts with different FLs in listening and word pronunciation. The effects of functional load on ESL learners’ perception of vowel contrasts are investigated in terms of both input and output dimensions. The overall findings indicate that high FL vowel contrasts are more likely to be captured in listening and more consciously distinguished in pronunciation, a piece of evidence proving the necessity of applying FL principle to English pronunciation teaching.
